I'd be utterly amazed if you (or I) can cut a slot dead on size with either a saw or a router. The best chance you will have is with a very rigid machine setup, like a mill, and a custom ground (or lucky stock) small diameter cutter run at relatively low speed, like a slotting cutter. Ron N Ron and Others I picked up a cross sliding vise for about $100.00 from MSC. It is an import but built well enough for tolerances that this knuckle/shank project requires. The gibbs can be adjusted and the lead screws are OK, so it travels well in the X, Y axes. It gets bolted to the drill press table and converts the press to a poor man's milling machine. Tilt the press table 90 degrees with the vise bolted on and slotting cutters can do their job. It takes a few minutes to index the vise to the spindle and it yields consistent results. My drill press has square table that I machined the sides parallel and square to the column. I use a screw less machinists vise with it frequently. It is very tight, no warping jaws when you clamp things into it. Paul C
